- colors and fill patterns used in various maps to portray quantitative variables with a sequential or diverging pallete, and hatching patterns to convey quantity within a given color
- Cheysson fonts to reflect some character of the hand-drawn style used in these images.
At present, it is just a work-in-progress, awaiting translation from the original sources to R, most likely using the framework of the ggpattern and ggthemes packages. This README simply documents the sources and steps so far.

David Rumsey acquired the complete set of the Albums de Statistique Graphique, and placed them online in the David Rumsey Map Collection
-
From this, RJ Andrews, Classic Map Color Design: Recreating palettes from the Albums de Statistique Graphique., identified 25 maps from the Albums, containing a variety of colors and fill patterns. He then constructed SVG patterns in this Github repo.
-
Tom Shanley, Cheysson Color Palettes. A collection of SVG colors and patterns for Observable.
-
Kenneth Fields, The style of Émile Cheysson, packages these for ArcGIS Pro.
The 25 maps use a variety of sequential, diverging and categorical palettes. These are named for the album year and plate number in the figure below, for example 1880 map 7 for the upper left figure.
RJ Andrews abstracted the color and patterns from these images into SVG files, represented in the figure below. He named these according to days of an Advent calendar, so, for example, the palette for the image "1880 map 07" was published for Advent Day Dec. 06, and is labeled "Dec.06-1880.07".
Tom Shanley used these SVG files for his Cheysson Color Palettes, and unfortunately named
them according to RJ's Advent Days. These are contained in the data-raw/observable/ folder,
with names like dec06.txt, for the palette of the 1880 Map 7.
Kenneth Fields created a set of five fonts to mimic the hand drawn lettering used
in the Albums. The reside in the fonts/ directory as .ttf files, and consist of
Cheysson Regular, Cheysson Italic, Cheysson Sans Caps, Cheysson Outline Caps,
and Cheysson Title.
TODO: Figure out if these fonts can be installed from the package, or give instructions.
There's not much here yet, but you can install the development version of ggCheysson like so:
remotes::install.github("friendly/ggCheysson")This is a basic example which illustrates that there's not much that can be done yet.
library(ggCheysson)
